Example #1 ftp_pwd() 例子
<?php
// set up basic connection
$conn_id = ftp_connect($ftp_server);
// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
// change directory to public_html
ftp_chdir($conn_id, 'public_html');
// print current directory
echo ftp_pwd($conn_id); // /public_html
// close the connection
ftp_close($conn_id);
?>
This function doesn't always go to the remote server for the PWD. Once called the PWD is cached, and until PHP has a reason to believe the directory has changed any call to ftp_pwd() will return from the cache, even if the remote server has gone away.
